Disassemble,Clean and Inspect Ground splice pack at grounding point 7 (Top of chassis behind left hood henge)

Clean and Inspect grounding point 9, should be 1-3 wires on top of chassis under battery heat shield.

Clear codes,Drive and see what happens!

Active Handling Warming Up, Failed Smog, Incomplete test - solved

Failed smog 2 weeks ago, incomplete test, HP Tuner confirmed all emission test incomplete.

Car 1999 C5 Auto, running well, no codes.

Checked all fuses, relays, ground points, pulled console - checked voltages everywhere...looking too deep!!!!

Only tale was Active Handling Warming Up displayed for the last 6 months - just got to be normal.

When temp IAT not outside is below 14 - active handling display warm up as a warning for 7 mins.

HP Tuner showed Intake Air Temp. of -39? WTF.

Replaced IAT Sensor 25$ part. Passed smog - active handling warmup gone.
